CAR-LOADER.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed October 14. 1905. Serial No. 282,776.

To all whom it may concern:

United States, residing at Fairmont, in the county of Marion and State of West Virginia, have invented certain new and useful Improvements in Oar-Loaders, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in mechanisms adapted to distribute material or deliver material to a desired point, it being particularly adapted for the purpose of loading box cars.

The invention embodies improvements upon the mechanism set forth and claimed in my joint application with O. F. Ice, Serial No. 260,140, filed May 12th,

' 1905, for car loader, 2'. e. of the type of loader in which there is a rotatable material receiving casing and a rotary material distributing shovel therein.

Of the several objects of the invention, those of most importance are the providing of carriage moving means interposed between a motor on the carriage and the carriage supporting wheels for causing the forward and backward travel of the carriage, and also the providing power transmitting means interposed between the motor and the rotatable casing adjusting sleeve for effecting the adjustment of the casing. Preferably both the carriage moving means and the casing adjusting devices are operable and controllable from a point without the car when the carriage is introduced into the car so as to maintain the casing in proper working position therein, and both are actuated by the same motorwhich drives the rotary shovel within the casing.

Other objects of the invention will be disclosed from the description of a box car loader embodying my improvements which I have chosen for the purpose of illustration.

Figure l is a plan view of a car loading or material propelling and distributing mechanism embodying my improvements, part'of a car being shown more or less conventionally. Fig. 2 is a side elevation of the parts shown in Fig. 1 withdrawn from the car. Fig. 3 is a vertical cross-sectional view illustrating the brake mechanism in elevation. Fig. 4 is a view partly in section and partly in side elevation of a portion of the mechanism. Fig. 5 is a sectional view through the casing in which the distributing head is mounted.

In the drawings I have shown the operative parts of the mechanism supported upon a platform or in a housing at the side of the car track, this being indicated as a whole by A. There is also conventionally shown in Fig. 1 a portion of an ordinary box freight car at B. Upon the platform A there is provided a track having rails A with stops A at front and rear thereof, and upon these rails there is mounted a truck 01' carriage having the platform O and the truck wheels 1), D fitted to the rails A. The rear or outer portion of this truck frame is indicated by C and the forward or inner Be it known that I, JOHN H. HUHN, a citizen of the portion by C 5 ing the rear end of the shaft G into a sleeve or hub H Upon the rear part (1 is mounted a motor E which for many reasons is preferred to be of the form of an electric motor coupled directly to the driving shaft of the distributing head or shovel. The armature shaft F projects somewhat forward beyond the motor and is connected to the driving shaft G by a universal coupling H. he driving shaft G should be capable of being relieved of excessive load after a certain limit of resistance has been reached. Such yielding and stoppage of the shaft may be provided for by having a friction clamp coupling interposed between the driving shaft element and the part at H, but I find that by inserton the coupling H and securing it therein by a breakable device such as a wooden pin h, that the necessary factor of safety for the driving mechanism calculated to yield or give away at a certain point under an excessive load is supplied.

The shaft G is extended forward a relatively long distance and is passed through a hollow sleeve or shaft I. The latter is so formed or providedwith bushings, that long bearings therein shall be furnished for the rapidly rotating interior shaft G, and at these bearings the sleeve or hollow shaft I is mounted in external bearings at K, K. Between the bearings a large oil cavity is provided because of the diameter of the interior shaft G being considerably smaller than the interior diameter of the surrounding sleeve or shaft I. The lubricant is supplied from a receptacle 1 and tends to flow in either direction and finally reaches the interior bearings of the driving shaft.

The propelling apparatus or distributing devices comprises an external rotatable casing or shell, indicated as an entirety by L, and an interior rotary head or shovel indicated, as a whole, by M. The shell or casing part L is formed of a support or carrier Z at the rear end, a ring wall or annulus l at the front end, a peripheral wall Z and binding or clamping devices 1 With ref erence to the design and construction of the casing L and the rotary head or shovel M, they may he of any well known or preferred type, and for this reason I do not consider it necessary to describe them in detail. The peripheral wall Z of the casing has an opening I therein through which the propelling blades or vanes of the rotary head or shovel drive or force the material to be distributed. The blades or vanes upon the rotary head should be of somewell known form adapted to operate efliciently and satisfactorily in either direction in which they may be rotated.

I have found it decidedly advantageous, especially where the casings are large and heavy, that some sort of motive power be utilized for rotating the hollow shaft or sleeve I to adjust the rotatable casing L so as to po- 110 sition the opening Z therein to distribute the material in any direction desired within the car. For this purpose I have found it convenient to interpose power transmitting devices between the motor for driving the rotating head or shovel M and the said hollow shaft or sleeve 1. In the drawings this train of power transmitting devices is indicated as an entirety by N. Of it n represents a friction disk rigidly secured to the shaft G and having a front vertical friction face a. 0 indicates a wheel having a hub 0 rigidly secured to a portion 1' of the shaft I which extends rearward from the bearing K, the hub 0 preferably abutting at its front end against the rear end of the said bearing, and

.at its rear end being closely adjacent to the vertical friction face of the wheel n but not touching it. p is a friction shoe or block mounted within the wheel 0 arranged to slide transversely thereof between the inner rim wall and the hub of the wheel, and adapted to have its rear face 10 engage with the vertical friction face n of the friction wheel n. R indicates as an entirety a hand controlled means for effecting the movement of the friction block or shoe p so as to cause it to effectively engage with and rotate with the friction wheel 11. This friction shoe controlling device is preferably formed in two parts, it comprising a disk 1" having a forwardly projecting cam surface, a disk 1' having a rearwardly projecting cam surface 7' adapted to engage with the cam surface on the rear disk 1', the said part r having a forward extending shaft r to the front end of which is rigidly secured a hand lever 1"". s is a bearing and abutment plate secured to the front face .of the wheel 0 and having a bearing s in which the shaft part T of the cam element T2 is mounted. It will. be observed that when the operator grasps the hand lever r and swings it about the axis of the shaft 1' that the cam surfaces of the disks 1", 1", assuming that the handle was in a vertical position, will engage with each. other and tend to force the parts of the friction shoe controlling element apart and, as the front part 7' is held against forward movement, the rear one 7 will move and will press the shoe p into engagement with the vertical friction surface a of the friction wheel n. If the wheel 12. is rotated, sufficient pressure can be applied to the hand lever r to cause a frictional engagement between the friction shoe p and the said friction wheel a which will be sufficient to cause the wheel 0 to travel with the wheel n and consequently to turn the hollow shaft or sleeve I and rotate the casing L.

The periphery of the wheel 0 is recessed as indicated at o to receive a brake band T. One end of this brake band is connected by a pin t to a block U rigidly supported in any suitable manner on the carriage frame and preferably beneath the wheel 0 and the other end of the said brake band is mounted upon an eccentric V carriedby a shaft V loosely mounted at either end in the said block U.

V is a hand lever for controlling the rotation of the shaft V and the operation of the eccentric V so that it will draw downward the end of the brake band T connected to it and cause the clamping of the said band upon the wheel 0.

I have also found it desirable to control the forward and backward travel of the truck 0 by means of motor driven mechanism, and with this end in view have interposed between the motor E and the carriage rum is indicated as an entirety by IV. Of this train of power transmitting devices W, to indicates a bevel gear rigidly secured to the shaft G. As shown it may be formed integral with the friction wheel n and projoct rearward therefrom. to is a bevel gear splined to a vertical shaft X in suitable bearing standard X on the carriage frame, the said bevel gear to being adapted to be moved up and down on the said vertical shaft. For this purpose I have provided an eccentric lever Y pivotally mounted at y at one side of the bearing standard X and adapted to have its under surface engage with an offset wall 90 on the said bearing surface and to have its upper surface engage with the under .surface of the bevel wheel w or its hub. X' is a worm secured to the lower end of the vertical shaft X and meshing with a worm gear X rigidly secured on the aXle to which the front car wheels D, D are rigidly secured. Preferably the bevel gears 10 and w are friction gears although they may be toothed gears if desired.

In operation in order to cause either the forward or backward travel of the carriage, the operator sets the motor E to rotating in the desired direction and then by bearing down upon the lever Y throws the eccentric thereon so as to cause the upward movement of the gear to and its engagement with the gear w. Power is then transmitted to the track wheels D, D so as to rotate them in the desired direction. The carriage will then travel along its track way in the desired direction and will cease so traveling when the operator releases the pressure on the lever Y.
